DYEING APPARATUS.

Application filed November 9, 1908.

Specification of Letters Patent.

1'0 all whom it may concern:

Be it known that we, JOHN C. EVENDEN and CHARLES FRoHLIoH, citizens ofthe United States, residing at Amsterdam, in the county of Montgomeryand State of New York, have invented certain new and useful Improvementsin Dyeing Apparatus, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to apparatus for dyeing, scouring, bleaching orotherwise treating fibrous material, and it more particularly relates toan improvement in apparatus of this character adapted for dyeingmaterials such as raw cotton and wool, hosiery, knit underwear and cops.

One of the objects of the invention is to provide apparatus such. thatthe material treated will be uniformly saturated or impregnated with thedye.

Another object is to provide dyeing apparatus whereby the material to bedyed as well as the dye liquor may be easily and quickly handled.

Another object is to provide mechanism whereby the dye liquid may beutilized repeatedly if desired, and which ail'ords improved facilitiesfor maintaining or changing the temperature of the dye liquid.

' A further object is to provide a machine which will occupy a minimumamount of space and which may be operated with little care or attentionon the part of the operator.

Other objects will be in part obvious, and in part pointed out herewith.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims:

In the accompanying drawings wherein is illustrated one of the variouspossible embodiments of our invention, Figure 1 is a centrallongitudinal section of a machine constructed in accordance therewith;Fig.

.2 is a horizontal sectional view taken substantially on the line 2-2Fig. 1.

Similar reference characters refer to similar parts throughout bothviews of the drawings.

Referring now to the drawings, wherein we have shown our improvedmachine adapted for dyeing yarn in cop form, 1 denotes arectangular'tank mounted upon suitable supports 2 which may rest uponthe ground or floor. This tank, which is adapted to hold the dye liquorand the material to be dyed, is provided, in the present instance, withopenings as at 3 and 4, respectively, in its upper wall near either endthereof, said openings being adapted to be closed by cover plates 5 and6, respectively. Cover plates 5 and 6 are fastened tightly in place asby means of bolts and nuts 7 so as to provide against the escape of thedye liquor during the operation of the machine.

Located within the tank 1 directly beneath each of openings 3 and 4 areperforated receptacles 8 and 9, respectively, said receptacles beinglightly spaced from the end walls 10 of the dye tank as by means ofspacing members 11, said spacing members and the bars 11 formingsuitable compartments in which the receptacles may be set.

12 denotes a closed tank from whichthe dye liquor is supplied to the dyetank through valved conduits 13 which lead into said dye tank at pointsintermediate said receptacles. The su ply tank is also connected withthe end walls 10 of the dye tank by means of conduits 14 and 15,suitably valved, as at 16, which are branched to enter the upper andlower portions of the tank at the ends thereof. The dye liquor may bemaintained at the desired temperature by means of a steam conduit 17located in supply tank 12, and the dye liquor may be supplied to tank 12through a conduit 18 leading into the upper portion thereof. A drainconduit is provided at 19 leading from the bottom wall of the supplytank and a relief or safety valve is provided at 20 in the upper wall ofthe supply tank.

A receptacle 21 is provided exteriorly of the dye tank and supportedthereon as by means of brackets 22, said receptacle being provided witha removable cover portion 23. This receptacle is adapted for holding asample of the material to be dyed, and is connected with the dye tank atpoints adjacent receptacles S and 9 by means of conduits 24 and 25,respectively.

A. piston 26 is located within the dye tank 1 intermediate receptacles 8and 9. Piston 26 in the present instance com-prises end plates 27 and28, respectively, of rectangular shape to conform to the interiorconformation of the dye tank, spring pressed blocks as at 29, beingprovided for preventing the passage of the dye liquor between the pistonand the walls of the tank. Bars 30 and 81 provide a rigidaconnection forplates 27 and 28, respectively, said bars being provided with teeth asat 31, with which cooperates a mutilated gear 32 mounted upon a shaft 83adapted to be driven from a suitable source of power.

It will be understood that by means of the construction last abovedescribed a rotation of gear Wheel 32 will operate to reciprocate thepiston in the dye tank. It will also be understood that mechanism otherthan mutilated gear construction may be employed for reciprocating thepiston.

Conduits 34 which will lead from the bottom of the dye tank may beutilized for draining the tank of the spent dye liquor or for conductingthe same to a suitable receptacle when it is desired to utilize the samefor another dyeing operation.

Having thus described the construction of this embodimentof ourinvention, the operation thereof may now be understood.

The material to be dyed is placed in the receptacles 8 and 9 which, forconvenience, are made removable, enabling them to be lifted from the dyetank for the purpose of loading or unloading. The receptacles are theninserted in their compartments in the end portions of the dye tank andsaid tank is then closed by means of the cover plates 5 and 6. At thispoint it may be noted that while we haveshown the dye tank open at thetop, such openings may be formed in the side walls if desired, suitableclosures being provided for rendering the tank water tight. After thedye liquor has been heated to the desired degree in the supply tank 12it may be discharged into the spaces bet-ween the piston and thereceptacles 8 and 9, re spectively, by opening the valves in thecondui'ts 13. The apparatus is then ready for operation. It will beunderstood, of course, that tank 1 will be kept filled with the dyeliquor, which may be discharged therein by gravity or forced therein bymeans of suit able pumps. During the reciprocation of piston 26 the dyeliquor will be forced alternately in opposite directions through thematerial in the receptacles 8 and 9, the dye liquor, after passingthrough the receptacles, flowing into the supply tank 12 through theconduits l4 and 15. A similar circulation of the dye liquor will takeplace through the sample receptacle 21 by means of the conduits 24 and25. In other Words, the dye liquor will circulate alternately inopposite directions through the entire apparatus, the desiredtemperature thereof being at all times maintained by means of the steamconduit 17. l/Vhen it is desired to unload the machine, the valves andconduits 13 are closed and the dye tank drained through the conduits 34.The cover portions are then unlocked and the receptacle-s S and 9removed from the storage tank and unloaded, when the dyeing operationmay be repeated upon fresh material. It will, accordingly, be seen thatwe have provided apparatus especially well adapted to attain, amongothers, all the ends and objects above pointed out, in an extremelysimple, yet efficient manner. The locating of the piston within the dyetank effects an economy in the use of space, and the provision of thesample box exteriorly of the dye tank results in a great saving of time,since it permits the material being treated to be examined withoutmaking it necessary to suspend the operation of the machine while thedye tank is being opened for inspection.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.
